Quad Bike


  • The Main objective of Designing & Manufacturing  of the Quad Bike  is to increase the Advancement in the Automobile Field.
  • To design a quad that can handle a wider variety of terrain than most other vehicles.
  • To design and develop a vehicle that meets all the safety needs according to the norms set by the SFI.


As the name says it all;  is a true symbolic word for combining Mother & GOD

About FMAE & SFI:-

Fraternity of Mechanical and Automotive Engineers.

The organizing team of FMAE comprises of individuals with 7-8 years experience in organizing design challenges throughout the nation.

The SFI Foundation, Inc. (SFI) is a non-profit organization established to issue and administer standards for the quality assurance of specialty performance and racing equipment.

Design of Quad: 

The following design methodology was used during design:

  • Requirement
  • Market survey
  • Design calculation and iteration
  • Modelling and analysis
  • Preparation of mock chassis
  • Final manufacturing
  • Testing
  • Acceptance

Material selection

4130 Chrome Moly Steel is the best suitable material, it we selected over 1018 Steel because 4130 Steel has a greater strength to weight ratio. Along with material selection, tube diameter was also taken into consideration.

Following is the comparison table used for material selection:

Some more highlight on AISI 4130 material:

  • The material AISI-4130 (Annealed at 840° C) used in the frame design because of its good weldability, relatively soft and strength as well as good manufacturability.
  • AISI 4130 has been chosen for the chassis because it has structural properties that provide a low weight to strength ratio. Presence of chromium makes it a corrosion resistive material. 1 inch diameter tube with a thicker wall is used. It is assured by analysis in ANSYS simulation software.
  • Different cases of impacts were considered for the analysis of the chassis:
